MATRIX-SETTING Ann rvrn-nrnn-oasrrne MAcIiINnQ Application filed December 27, 1927, Serial No. 242,862, and in Germany April 18,. 1925.

This invention is for improvements in or relating to matrix-setting and type-line casting machines of the kind wherein the matrices arev assembled in line by feeding mechanism which presses the matricesinto a guideway against an assembling-abutment which is movable in the direction oi the length of the line and wherein the'assembled line of matrices is moved towards .themould by a transferring-abutment. It is usual in this kindof machine for the assembled line of matrices to beconveyed between the assembling-abutment and the transferringabutm-ent to the casting-carriage; and for these two abutments to be returned to their initial positions after the carriage has been moved towards the mould. It will be seen that with such an arrangement a new line of matrices cannot, be assembled until the asinitial position; 7

An object of'this invention is to provide a construction which will permit a line of matrices to be assembled while the previous line is on its way to the casting-carriage or r to the mould According to this invention, a matrix-setting and typeeline casting machine oft-he kind described is characterized in that means are provided for automatically withdrawing the assembling-abutment from in front of an assembled line of matrices and for returning it to its initial position before or during the transference of the line, and in the provision of a forward transferringabutment which is arranged to replace the assembling-abutment when the latter is withdrawn, which forward transferringabutment, together with the first said and rearward transferring-abutment, conveys the assembled line of matrices towards the mould. Means are provided for automatically withdrawing the said transferring-abutments n-om contact with the line of matrices before the casting-carriage is moved and means for returning the transferring-abutments to their initial positions.

In order that the forward transferringabutment may replace the assembling-abutment these two parts are so disposed in relation to one another and so formed that they -may be made to engage at the same time the forward end of the assembled line of matriees, for example one of them maybe slotted sembling-abutment has been returned to its -in which and the other arranged to enter the slot. Preferably the assernloling-abutment iswithdrawn after or at the time of the engagement of the forward-transferringabutment with the line of matrices.

' A convenient arrangement for w1thdraw-.

rices and in providing astop carriedon a fixed partot the machine and so disposed in the path of travel of a part otthe said finger as to swing the finger clear of the line of matrices when the line is being moved towards the casting-carriage; The details of the construction of said finger are clearly? setout inthe accompanyingdescription of one embodiment of'this invention.

The forward transferring-abutment also preferably comprises :a finger pivota-lly mounted upon a carriage which is is arranged to move in the direction of thelength of the line of matrices, which finger is retained in contact with the 'matrices by means of a pawl until after'the line has been conveyed into the casting-carriage whereupon afixed stop releases the pawl and "the finger is swung away from the matrices under the action of a spring; l L

Gther features-of the inventlon will be apparent from the following description of one embodiment of thisinvention.

In :the following. description 0t a inatri Q setting and type-line casting machine, reference is made to the accompanying drawings,

Figure 1 is a side elevation ofthe part oif theinachine in which the matrices are fed into the assembling-guide and also the casting-carriage Wlll jh del vers them to the mould, not shown; The parts are in position ready for transferringthe line to the casting-carriage; v

Figure 5'is a plan view of the arrange- .ment of Figure also showing certain parts in section; I

Figure 6 is a similar view to Figure 1 but showing the line of matrices in position in the casting-carriagewith the forward trans ferring-abutment out of contact therewith;

Figure 7 is a similar View toFigure 6 showing the casting-carriage at the commencementof the downward movement towards the] mould and about to release the forward transferring-abutment so that, it

may be returned to its initial position.

' The matrices after being released from their respective magazines are conveyed to the horizontal assembling-guide 2 in the usual manner by means of the collectingbridge and star-wheel 1 which latter partguides the matrices into the assembling guide. An assembling-abutment 3 is arranged to project vertically into the said assembling-guide and the matrices are pressed by the action of the said star-wheel against the said assembling-abutment. The assembling-abutment is mounted on an assembling carriage 4 which is arranged to slide horizontally and'the movement given to the abutment through the agency of the star-wheel and line of matrices is opposed by a spring 6 acting through a lever 5 secured to the said carriage. Thus when the abutment is withdrawn from the line of matrices the spring returns it to its initial position.

The construction of the assembling-abutment, as shown in Figures 8 to 11, comprises an upright member 7 which is secured to the assembling-carriage 4 and carries towards its upper end a horizontal shaft 8 which is arranged transversely above the said assembling-guide. An assembling finger 3 is carried at one end of saidshaft and projects downwardly into the said assembling-guide.

- To the other end of theshaft is attached a two-armed lever 9, 12, of which the arm 9 carries an adjusting-screw 10 which coopcrates with a stop 11 carried by the said upright member. The said assembling the said pin.

finger can thus be adjusted to take up an exact vertical position.- On the other. arm

12 there is pivotally mounted at 14: a stop plate 13. Said stop plate is provided with a curved slot 15, the curve of which is concentric with the pivot 14 A. pin 18 formed at the end of the shaft projects through the said slot. The said stop plate is pulled downwardly by means of a spring 17 which is secured in such a manner'tothesaid plate that the left-hand end of the slot, as viewed in F i 'ure 9, is maintained in contact with A lug 16 is formed 'on the said plate above the slot, as viewed in Figure 9, Which shows the position ofthe assembling finger 3 at a time when it is supporting theline of matrices. The bottom ofthe plate at the right-hand sidev 19 is arranged to engage with anadjustable stop 20 carried by the said upright r e Vhen the matrices are being pressed during the building up of the .line against'the assembling linger in a direction shown by the rrow X in Figure 9, the finger is prevented from being moved outwardly by reason of the factthat theside 19 abuts against the" said adjustable stop 20. VVhenthe assembled line of matrices is conveyed towards the casting-carriage in thedirection'as indicated by the arrow Y in Figures 9, 10 and 11. the lug 16 engages a stop 28 (shown inFigures 1 to 3) carried by a fixed part of the machine; the assembling carriage tis thus arrested and the stop plate 13is caused to turn about the pin 14 until the pin 18'contacts with the r ht-hand end of the slot as V 2'3 shown in I igure 10 at which tune the righthand bottom side is withdrawn from'the adustable stop 20. Continued movement of the assembling carriage causes the stop plate to rotate the shaft 8 whereby the finger 3 is swung upwardly out of the assemblingguide, shown'in Figure 11 so that the line of matrices is now able to'pass below the said finger. At this moment the forward end of the line of matrices is engaged by the forward trtnisferring-abutment 30. -lVhen the whole line has passed below the assembling finger the latter is pulled back into the vertical position by the springl'i' and the as- 1 5 sembling carriage 4 is withdrawn to its original position by the spring 6 already set fortl. 1 The finger is thus oncemore ready to form a new line of matrices. The line of matrices is moved. into the casting-carriage by means of the rearward transferring-abut- V ment which comprises a rearward-finger 21 pivotally mounted upon a rearward transferring carriage iVhilethe line ofmatrices is being assembled the finger 21 is heldin 12 a position below the star-wheel l'by a springcontrolled pawli23 which is mounted :on the carriage 22. Movement is'give'n to the carriage 22 for the purpose of conveying the line of matrices tothe castingcarriage mov ing means 24. A projection on the moving means is arranged at the commencement of the movement of the chain to engage the pawl23. The finger 21 'is thereby released and is pushed upwardly by the said spring so as to engage the rearward end of the assembled line of matrices, as shownin Figure 3..

As already stated, at the moment at which the mger of the assembling-abutment is swung away from the line of matrices the forward end of the said line is engaged by the finger of the forward transferring-abutment which together with the finger 21 of the rearward transferring-abutment holds the line together. I 7

The construction of the forward transferring-abutment is shown inFigures 12 and 13 and comprises a forward transferring finger 30 which is mounted on a pin 36 carried horizontally by the forward, transferring carriage 31. The carriage is guided to move horizontally towards the casting-can riage which movement is opposed by a helical tension spring 32. As shown in Figures 4 and 5, said spring is secured-at its forward end to a part of the carriage and towards its rearward end passes through a bore in a lug 33 carried by a fixed part of the machine. The said bore is internally threaded so as to engage the convolutions of the spring. The said spring projectsrear- 'wardly from the said lug. Located axially within the saidspring is a rod the forward end of which, when the carriage is in its rearward position, rests against a part of the carriage, and the rearward end of which pin .is connected to the end of the spring which projects rearwardly from the -said lug. The spring and rod are enclosed within a tube-shaped channel 34:. It will beseen; with this arrangement that the rearward end of the spring may be arranged to act as a buffer for the rearward return movement of the carriage. Alternatively, he spring 32 may be made in two parts so that the tension spring attached to thecarriage and the buffer spring attachedto the right-hand end ofthe pin 35 are mounted in the lug 33 so as to be independent of one another. The forward transferring finger 30 is held in a vertical position by a pawl 37 ready for engagingthe forward end the assembled line of matrices, whichend is released from the assembling-abutment finger 3, as shown in Figure .13. The pawl is mounted on the forward transferring carriage 31 and engages with arecess 38 formed in the finger 30, and is retained in position by a spring. The said finger30 v is held in a vertical position until the assembled line of matrices has-been conducted to the furthest forward position in the casting-carriage. As soon as this position has been reached the carriage is locked against movement, as shown in Figure 6,

'by a pawl 39' which is spring-pressed. into engagement with a recess 40 formed in the carriage31, the said pawl being carried on a fined part of the machine; simultaneously the pawl 37-is mo-vedout-of engagement with the recess 38 in the finger 30 by means of a stop 11 also carried on a, fixed part of the machine. The 'said finger 30 is then swung forwardly away from the line of matrices by means of a spring-actuated pin 4-2 which is carried by the carriage 31. The movement of the said finger 30 is limited by the pawl 37 engaging with a second recess 4'3 therein. In this manner the forward end of the line of matricesis released from the said finger. At the moment that thefoiw ward end of the line of matricesis released, the finger. 21 is withdrawn from the rearward end of the line and is conducted back to'its original position. On the rearward journey of the finger 21 it passes beneath the finger 3 which is then directed vertically downwards and is swung downwardlyby the said finger 3 and locked in this downward position bythe pawl 23, and in. this position turns to beneath the star-wheel.

The line of matrices now in the casting.

carriage is conducted into the ca-sting potinued descent of the casting-carriage the stop 46 engages with the pawl 39-and releases it from the recess 40' in the: carriage 31 so that the latter is pulled back into its original position by the spring 32.

In Figures. 14 and 15 an alternative con struc ion is shown for the forward transferring abutment. A forward transferring finger 3O" isinounted'on a horizontal shaft 90 which is spring-pressed in a direction towards the forward end of theline of matrices. The forward end of the shaft is enby one end of a double lever91 which is mounted on the carriage 31; l/Vhen the assembled line of'inatrices is conveyed into the casting-carriage the movement of the carriage 31 causes the other end of the lever 91 to be engaged by the stop l1 whereby. the shaft 90 and finger 3O are withdrawn,

against the action of the spring, away from the frontof the line of matrices. The car 31 is retained in position atthe end of its travel by reason of a vertical spring pressed 'pin 93 which is mounted on the carriage snapping over the end of a bell-crank lever 95. The said end ofthebell-crank lever is spring-pressed upwardly by a spring 94, which spring is of less strength than the Jan spring of the vertical pin. The stop 46 on the casting-carriage is arranged on the downward movement thereof to engage the inclined face on theupwardly-directed arm 96 of the bell-crank lever whereby the arm 95 is lowered against the action of the spring 94 and the'spring-pressed pin 93 is pulled past it and releases the carriage 31. The second t-ransferringabutment is then again automatically restored to its initial position.
